After the September 11, 2001 attacks in New York City, Conroy participated in relief efforts by volunteering to cook for police officers and firefighters. During an audio commentary on Batman: Gotham Knight, Conroy expressed his surprise at the reaction of the emergency service workers to his presence. At the behest of another cook, Conroy called out from the kitchen to the dining area in his "Batman voice", reciting the iconic line, "I am vengeance! I am the night! I am Batman!" (from the Batman: The Animated Series episode "Nothing to Fear"[12]) This was greeted by cheers and applause from emergency service personnel, many of whom had been fans of Batman: The Animated Series during its airing in the 1990s. Conroy confessed to being humbled and deeply flattered by the reaction.[13]

In preparation for the theatrical release of the 2012 live-action film The Dark Knight Rises, Conroy re-dubbed Christian Bale's Batman lines for an animated version of one of the film's trailers.[14]

Conroy stated at the 2013 Dallas Comic Con that he had been working on "the next Arkham", leading to rampant speculation that he would reprise his role as Batman in Batman: Arkham Origins. In June 2013, however, it was confirmed that Conroy would not be involved in Arkham Origins, meaning Conroy may have been referring to an yet-unannounced game from the Rocksteady Arkham series.[15] In March 4, 2014, a new Arkham game titled Batman: Arkham Knight was announced with Conroy reprising his role.[16]

He confirmed on Twitter that he filmed a role on Tim Daly's web seriesThe Daly Show,[17] where Conroy parodied his role as Batman in a fight with Daly parodying Superman (whom Daly previously voiced in Superman: The Animated Series).[18]
